MCU Redundancy

The Central Server Service is designed to monitor the activity of assigned pairs of MCUs, so if one MCU in the pair encounters a problem that prevents it from running conferences, the other MCU will take over smoothly.

In Central Server Service environment, as described in Figure 4-1, MCU A and MCU B are both registered in the gatekeeper with the same prefix and they are designated as backup to each other in the WebCommander Central Server Service.

The Central Server Service monitors both MCUs. When a new on going conference is created on one MCU (for example, MCU A), the Central Server Service automatically copies this conference to the second MCU (for example, MCU B) with the prefix *bck_. In the same way, when new reservations and Meeting Rooms are created on one MCU they are automatically copied to the second MCU.
